Abstract

PURPOSE
To report 2 cases of Actinomyces infection in a hydroxyapatite orbital implant with a motility peg. CASE SUMMARY: A 44-year-old male and a 55-year-old male who underwent evisceration and implantation of a hydroxyapatite implant in the left eye 17 and 15 years prior, respectively, presented with a conjunctival sac granuloma with discharge and bleeding of 1 year duration. Both patients had a history of motility peg implantation. A large-area of the hydroxyapatite implant was exposed after removal of the granuloma. The previous orbital implant was removed, and the exposed area was covered with a dermis fat graft in both patients. On histopathological examination, Actinomyces infection in the orbital implant was observed in both patients. CONCLUSIONS: To the best of our knowledge, this is the first case report of actinomycosis of hydroxyapatite orbital implant in Korea. In a patient with a porous orbital implant, the possibility of Actinomyces infection of the orbital implant should be considered after a long-duration and large-area exposure of the implant.
